How do you seperate device libraries with iTunes?
I backup 2 iPhones, 2 iPods and an iPad onto an iMac. To prevent cross-over of the apps, songs, pics and such I have setup seperate user logins for each family memeber. Since I own two mobile devices (iPhone and iPad) I want to keep their content seperate, but when I sync with iTunes they merge. It was a easy enough to delete what I did not want, but what a pain to have to do that each time I sync. Is there a way to create seperate content libraries for each device on iTunes? If so, how do you select which library to use?
